JOSEPH DEMYEN, OF PHILADELPHIA, PENNSYLVANIA.

REEDING-MACHIN E.

Application filed July 29, 1913.

To (ZZZ whom it may concern:

Be it known that I, JOSEPH DEMYEN, a subject of the King of Hungary, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Reeding- Machines, of which the following is a speci fication.

My invention relates to new and useful improvements in reeding machines, and has for its object to provide an exceedingly simple and effective device of this character, whereby the warp threads may be readily and quickly inserted in the reeds of looms.

A further object of the invention is to con struct a threading hook which will carry the threads through the reed, and during its revolution move the carriage the proper dis tance for threading the warp in the proper place.

Another object of the invention is to provide a movable carriage on which is mounted the threading hook, the latter having a spiral body in order that the carriage may be moved along the frame as the warp is threaded .into the reed to provide means for withdrawing the warp thread from the threading hook and to provide a ram for pushing the ends of the warp threads against a suitable brush or adhering member.

Another object of the invention is to provide an exceedingly simple counter or indicator having both visual and audible signals which will indicate to the operator, when a change is to be made in the number of warp threads to be inserted in the reed and the correct number to be inserted between the time signals are given.

A further object of the invention is to pro vide means for operating both the visual and audible signals at predetermined times.

A further object of the invention is to provide means for operating the reeding machine so that the same may be run forward or reverse, should anything become disarranged.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail. referring Specification of Letters Patent.

by numeral to the accompanying drawing forming a part of this specification, in which Figure 1, is a side elevation of my improved reeding machine showing portions thereof broken away to clearly illustrate the construction. Fig. 2, is a longitudinal sectional view of one end of the threading hook shaft showing the construction by which a threading hook may be readily and quickly removed or replaced. Fig. 3, is a front ele vation of the reeding machine having portions thereof broken away to illustrate the construction. Fig. 4, is an enlarged side elevation of the carriage portions thereof be ing broken away to illustrate the construction and showing a broken section of the frame to illustrate the relative position of the carriage to the frame brushes and reed. Fig. 5 is a plan view thereof, showing the carriage removed from the frame, and having portions thereofbroken away to clearly illustrate the construction. Fig. 6, is a view similar to Fig. .l from the opposite end, showing the threading hook receiving the warp thread and the position of the other elements at that time. Fig. 7, is a similar view showing the threading hook in another position and the rams bringing the warp thread into engagement with the brushes and having portions broken away to illustrate the construction. Fig. 8, is a perspec tive view of a threading hook, made by spi rally winding sheet metal; and Fig. 9, is a similar view of a threading hook, made by coiling a wire, steel tape or similar element upon a hearing or spider.

In carrying out my invention as here embodied, 2 represents the feet carried by the supports 3 which are formed from two members 4t and 5, the latter telescoping into the former and being held in its adjusted position by a set screw 6. These supports are braced by a cross pipe 7 and support the frame 8 comprising end rails 9 and side rails 10 and. 11, which are adjustable toward and away from one another by means of the slots 106 in the end rails, said slots having registering therewith a bolt 107 or its equivalent, on which is threaded the nut 108, the latter adapted to hold the slotted members in their adjusted positions. The side rail 11 is formed of channel iron, forming upper and lower guides 19. and 13 respectively, between which runs the carriage 14 provided with an upper and lower bracket 15 and 16 at each end thereof, on which are journaled the rollers 17 adapted to enact with the faces of the guides 12 and 1.3, in order to reduce the friction between the carriage and the guides and the lower brackets 15 and 16, and further supports a roller 18 which runs upon the edge of the guide 13, thereby supporting the carriage.

In the carriage is mounted a gear 19 through which passes the squared operating shaft 20, the latter being journaled in the end rails 9 of the frame and having motion transmitted thereto as will be hereinafter described. The gear 19 meshes with the intermediate gear 21., which is ournaled upon the shaft 22 and said intermediate gear in turn meshes with a smaller gear 23 mounted upon the threading hook shaft 24, and another small gear 25 mounted upon the drag hook 26, so that through said chain of gears motion is transmitted to the threading hook 27, and the drag hook 28. The threading hook 27 is provided with awarp thread receiving notches 29 and a spiral body 30, which as shown in Fig. 8 is formed by coiling a strip of flat relatively thin metal having a squared opening 31 at the center thereof, so that it may be mounted upon the threading hook shaft 24.

In Fig. 9 a slightly modified form of threading hook is shown in which the hook proper and its body is formed from a single piece of Wire coiled upon a spider 32, the latter being provided with a squared opening 31, so that it may be mounted upon the shaft 2%.

as the reed-dents are often of different sizes it is generally necessary to replace one threading hook with another of difierent size, and in order to readily accomplish this, I provide the end of the threading hook shaft with an opening 33 having an extension opening 34 in which is inserted one end of the sprin catch'35 having a nose 36 on its outer end, in order to prevent the accidental displacement of the threading hook after being placed upon the shaft. In order to remove the threading hook the spring catch 35 is forced backward from its normal position, which will move the nose 36 thereof below the outer surface of the shaft 24: and permit the threading hook to readily pass thereover.

The drag hook 28 is provided with a thread engaging extension 37 and its opposite end is bifurcated as at 38 and said bifurcated end is pivoted to a collar 39 mounted upon the shaft 26, said collar being held in place by set screw 40. The drag hook 28 is normally held in the position shown in Fig. 5 by a spring 41 mounted in another collar 12, also mounted upon the shaft 26 and held in place by a set screw 43.

During the revolution of the drag hook 28 the threading hook 27 lies in its path of travel, and in order that the drag hook may pass the threading hook I provide a cam track 44 having an incline which will swing the outer or free end of the drag hook away from the threading hook and permit said drag hook to pass said threading hook, and when said drag hook is at the limit of its outward movement, it rides upon the antifriction roller 4:5 and then quickly drops back upon the reverse cam track &6.

When the operation of the device is reversed the drag hook 28 rides upon the reerse cam track 4-6 and then over the antifriction roller 45 returning to the cam track 44 after the drag hook 28 has passed the threading hook 27. After the threading hook 27 has inserted the warp therein in the reed-dent, the end of the warp thread is engaged by the drag hook 28 and carried around the brush s 4:7, which are secured to the rail 10 of the frame, then the end of said warp thread is engaged by the wire rams 18 and 49, and pushed against the brushes by their outward movement. Said rams are slidably mounted in the guides 50 and secured to the carrier 51, the latter having an opening 52 with which registers the tongue 53 of the lever 54 journaled at 55, said lever being provided with an arcuate slot 56 in which operates the pin 57 carried by the crank 58 mounted upon the opposite end of the shaft 26.

teferring to Fig. 6 as the shaft 26 is revolved the crank 58 will move toward the right and downward, causing the pin 57 to draw the lever 5a to the right a short distance with the quick movement, after which said pin will ride in the slot 56 and gradually move the lever 5 1 to the right until said pin nears the lower end of the slot 56 after which the lever 54- will be quickly drawn backward or toward the left until said lever is in that position in which the center of the shaft 26 will be the center of the arc of the circle formed by the slot 56, so that the movement of the pin 57 in said slot 56 will have no action upon the lever 54 and the latter will remain stationary. The movement of the lever 54 above described will cause the rams 4:8 and 49 to be moved toward and away from the brushes at the proper time in order to bring the ends of the inserted warp threads in contact with said brushes, said brushes adapted to hold the ends of the warp thread to prevent said warp thread from becoming entangled in the mechanism.

59 represents an inverted L shaped clamp hinged to the side rail 8 as at 60 and a free end has mounted thereon a Z iron 61, which with the inverted L iron forms a longitudinal groove 62 adapted to receive one edge of the reed 63, the opposite edge of said reed when in place resting upon the upper edge of the side rail 11 and if found desirable may be fastened thereto in any suitable manner.

The above construction permits the clamp 59 to be moved away from the frame of the machine in the arc of a circle which will cause the reed 63 to be thrown up out of the way and permit the operator to put his hand into the machine for gathering up the ends of the warp threads and tie the same before entirely removing the reed.

The shaft 20 intermediate its ends is rectangular in shape in order that the carriage 1 1 may slide along thereon, but the ends of said shaft 20 are round in cross section, so that they may be journaled in suitable bearings in the frame, and on one end of said shaft is mounted the ratchet wheel 6 lpartially covered with a guide 65. At certain times the ratchet wheel is engaged by one of the pawls 66 or 67 pivoted to the pawl levers 68 and 69 respectively, said pawl levers being connected with the midway levers 70, 71, by the connectors 72, each of which is formed of two members 73 and 7 1, the former telescoping in the latter, so that they may be adjusted when the frame of the machine is raised or lowered.

The midway levers are pivoted by the bolt 75 or equivalent, which is carried by the plate 76 secured to the frame, and said midway levers are held in their normal position by the springs 77, one end of each of which is secured to the pin 78 carried by the frame and the opposite end of each is detachably secured to any one of the spaced pins 79, carried by the midway levers in order that the tension of the springs may be regulated. The movements of the midway levers are limited by the stops 80 and 81, the latter being adjustably mounted in the slots 82 formed in the plate 76, and said levers are connected by straps 83 and 81- to the pawl levers 85 and 86 having a number of spaced pins 87, whereby the straps may be adjusted if so desired. The pawl levers are mounted upon the pawl shaft 88 and the portion thereof which lies between the up rights +1: is squared and on this is slidably mounted the pedal 89 which is provided with a central aperture 90 in whichnormally rests a supplementary pedal 91 being pivoted or hinged to the main pedal as by a rod 92.

On the shaft 20 are also mounted sprocket wheels 93, over which runs a counting de vice 9%- comprising a pair of parallel endless chains 95, carrying cross bars 96, said cross bars having a number of spaced openings 97 adapted to receive pins 98, and as the sprocket wheels are revolved the counting device will be moved along to bring the pins in contact with the visual signals, each comprising a staff 99, which are engaged by the pins and which are pivoted at 100. In the let free ends of the stafls are mounted the semaphores 101, on which may be marked different numbers to indicate to the operator the number of warp threads to be inserted in each reed-dent, and each successive signal will also indicate when a change of the number of warp threads to be used takes place. An audible signal may also be provided in the form of a bell 102, which is rung by the hammer 103 pivoted at 104 and provided with a contact arm 105, with which certain of the pins 98 come in contact to raise, thereby operating the hammer 103.

The operation of the device is as follows :The warp threads are held in the right hand of the operator, and are then counted 01f and inserted in the threading hook 27 by the left hand, and after the warp threads have been inserted in the threading hook the pedal 89 is forced downward, thereby transmitting motion through the pedal lever 85, the strap 83, the midway lever 70, the connector 72, the pawl lever 68 and the pawl 66 to the ratchet wheel 64:, and the movement of the pedal will cause the nose of the pawl 66 to be disengaged from the guard 65, and engage the ratchet wheel 64 turning the same, which will cause power to be transmitted through the shaft 20 and the train of gears in the carriage to the threading hook 27, causing the threading hook to revolve one complete revolution which will insert the warp threads in'the reed-dent. During the revolution of the threading hook 27, the drag hook 28 is also revolved, and as said drag hook passes the threading hook said drag hook will engage the ends of the warp threads and carry them around toward the brushes 4:7, and as the drag hook 27 has passed the rams 47 and 49, said rams will be moved toward the brushes in engagement with the warp threads, thereby pushing the ends of said warp threads into engagement with the brushes 17, where they will be held until the operator is ready to tie their ends together. As the threading hook is revolved the coils of the body 30 are caused to enter each successive reed-dent, so as to properly open the reed and move the carriage along the desired distance, but in order to remove the strain from the threading hook I provide a counter-balancing weight 109, which is secured to one end of the cable 110 running over the groove pulley 111, the opposite end of the cable being attached to the carriage.

If during the operation of the machine anything should get out of order, or a reeddent be missed, it is often desirable to reverse the operation of the device, and in order to do this, the supplementary pedal 91 is drawn forward upon its hinging rod 92 and by depressing said supplementary pedal, motion will be transmitted through the pedal lever 86, strap 84, midway lever 71,

the connector 72 attached thereto, the lever 69, the pawl 67 to the ratchet wheel 64:, the remainder of the operation being identical with the description, except that the parts are moving in a reverse direction.

It will be noted that when the pawl 67 is operating in conjunction with the ratchet wheel 64, the opposite pawl 66 is upon the guard 65, so as to prevent any retrograde movement.

As the carriage 14 moves along by the revolution of the shaft 20, the counting device 94lis being operated, and the pins 98 are caused to engage with certain of the visual signal devices, which will raise the same to notify the operator that a change in a number of the warp threads is to be made, and by looking at the number upon the semaphores he can ascertain the number of warp threads to be inserted in the next succeeding reed-dents, and if found desirable as each change is to be made a pin can be placed in the counting device which will contact with the arm 105 to operate the hammer 108, for ringing the bell 102 which is an audible signal.

Of course I do not wish to be limited to the exact details of construction as herein shown, as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is 1. In a device of the character stated the combination of a frame, a carriage movable thereon, a threading hook to draw threads through a reed, a spiral body formed therewith adapted to register with the reed-dents for effecting a relatively lateral movement between the reed and carriage, a drag hook for withdrawing the threads from the threading hook and means for transmitting motion to the threading hook and drag hook.
